Signals that separate a sync that is merely slow from one that will never
finish:
- sync_acquire{missing_state_nodes_max, missing_tx_nodes_max, in_flight,
received_data_depth}: how many SHAMap nodes each in-flight acquire is
still waiting for. getMissingNodes already computed this and the callers
discarded it after a trace log. A count that stays flat means the
acquire is wedged; a shrinking count means it is progressing. Recorded
once per sweep, never inside the per-node walk, and reset when a tree
completes so a finished acquire does not read as stuck forever.
- shamap_cache_hit_rate{treenode}: hit rate of the in-memory tree-node
cache, which sits above the node store, so it is distinct from the
existing NuDB ratio. A cold cache on a fresh node sends every traversal
step to disk.
- sync_acquire_no_progress_total: timer ticks where an acquire made no
progress, previously only logged.
- sync_addnode_total{good,duplicate,invalid}: whether arriving nodes are
useful, duplicated or rejected, so wasted fetch work is visible.
- sync_acquire_source_total{local,network}: whether a ledger was served
from the local store or had to be fetched.
Adds getBad()/getDuplicate() to SHAMapAddNode and an acquireProgress()
accessor on InboundLedgers so the xrpld gauge can read these without
libxrpl depending on telemetry.
ledger_seq is deliberately not a metric label: it is unbounded. Per-ledger
identity stays on the ledger.acquire span; the metrics expose bounded
aggregates instead.
The full-below cache hit rate is not exported: KeyCache updates different
counters than getHitRate() reads, so it would always report zero. That
libxrpl bug is documented rather than papered over.

This change renames all occurrences of `namespace ripple` and `ripple::` to `namespace xrpl` and `xrpl::`, respectively, as well as the names of test suites. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
This change specifically removes all copyright notices referencing Ripple, XRPLF, and certain affiliated contributors upon mutual agreement, so the notice in the LICENSE.md file applies throughout. Copyright notices referencing external contributions remain as-is. Duplicate verbiage is also removed.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
C++ include guards are used to prevent the contents of a header file from being included multiple times in a single compilation unit. This change renames all `RIPPLE_` and `RIPPLED_` definitions, primarily include guards, to `XRPL_`. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
